Handle A PLC Latency Spike
Diagnose an intermittent robot-to-PLC handoff by preserving timing evidence before changing logic.
Intermittent fault One handoff fails every 70 cycles. Three logs disagree, and a CPU spike appears near the fault. Intermittent timing faults disappear when teams patch first and measure later. Timing contract Capture, contain, correct Handle intermittent handoffs by preserving evidence, bounding production risk, and then changing the contract or architecture. Shortcut Raise the timeout and hope. The correction is explainable and repeatable. A timing fix is only strong when it names the failed assumption and proves the new assumption under load. 01 Capture 02 Contain 03 Fresh case Do not erase the signal The team can reproduce the fault…
